Hans,
That works for the over-simplified case here, but fails in practice.
For a \startnarrower[left] paragraph, the mark is still in the main
margin, not the 'margin' of the narrowed paragraph. Also, the
placement of the text in the margin is wrong and not easily controlled
as with \llap and \rlap. The code started out more like:
\define\Mark{\color[middlegray]{\hskip.6cm\itb¿\ }}
\setwidthof{\Mark}\to\MarkWidth
...
\starttexdefinition stopBufTest
\startluacode
buffers.prepend("TestBuffer","\\dontleavehmode\\llap{\\Mark}")
\stopluacode
\setupnarrower[left=\MarkWidth]
\startnarrower[left,right]
\startparagraph
\inlinebuffer[TestBuffer]
\stopparagraph
\stopnarrower
\egroup
\stoptexdefinition
So I am still looking for a way to do this. Meanwhile I am trying to
understand Aditya's examples.
Turns out another answer was hidden in Hans's reply. The following seems
to meet my needs, but it may complicate other use of
\setupparagraphintro (which I don't recall seeing before), so it may not
be a generic solution.
An empty string works fine instead of the llaped marking shown here.
This is a less dangerous hack than redefining \par, but still may fail
in more complex documents when \setupparagraphintro is used elsewhere.
\starttexdefinition stopBufTest
\startnarrower[left,right]
\startparagraph
\setupparagraphintro[first][\llap{\Mark}]
\inlinebuffer[TestBuffer] \ (first: \First, arg: \Arg)
\stopparagraph
\stopnarrower
\egroup
\stoptexdefinition
Thank you, Hans.
(For a non-hack generic solution that does not interfere with other use
of \setupparagraphintro, surely there must be an easy way to apply
string.strip to the buffer.)
